The "object" is defined in the <types> element of the WSDL, it will be defined differently depending on the encoding "style" of the SOAP body and the structure of the "object". I have given you a link to an example of how one particular "object" might be represented using SOAP::Data - the OP in that case had given an example of the XML required.

If you are going to be working with SOAP you should at least be making some attempt to understand it - please review the documentation at http://www.w3.org/TR/2003/REC-soap12-part0-20030624/ at the very least in the first place.
